Thin air at high altitude, common small-scale wind turbines there, power will be greatly reduced, the original theory of design is possible only 800W to 700W. Coupled with long hours at high altitude sunshine, sand large wind turbine production materials are fast aging, a series of questions put by the researchers in the front. Open bow arrows without looking back. The organization of the set of all the wise crack research, the institutions created and the aerodynamic design of wind, Wind tunnel tests related to the theoretical calculation as well as product testing, field-site links, one by one scientific proof
wind generators blade is the most important one of the key components, which directly affects the exterior design of wind turbine on the wind energy absorption efficiency. In order to improve the utilization of wind energy function, they carefully analyze the local climate and environmental characteristics of the wind turbine blade design and carry out special processing, so that leaves Zuida wind energy utilization coefficient reached 0.480, Start wind speed less than 3m / s. This 800W wind turbine developed by the same wind turbine to increase power generation compared to 48W, power generation increased to 848W. When the sample machine developed by, the scientific research staff excitedly, a new reality problems are placed in front of them. How the research results into the final product to Dulan County, Qinghai Province, the local people? After many test, the the Institute and Green Haifanuoge Energy Technology Co., Ltd. reached an agreement and decided to Dulan County, Qinghai Province, a remote village as a product testing pastoral land, free of charge to local people. A typical wind turbine market price in 8000 yuan, while the per capita income of local people to reach 3, 4000 yuan. Free installation of wind turbines, which border pastoralists, the really great news.

April 2010, when the want to free installation of wind turbine Dulan County, Qinghai Province, the news reached the town of iron were added Kui village, the village excitement. When carrying wind turbine blades to get there, a lot of early Tibetan people waiting there. Some people still come from far away. That scene just as festive as barley wine, Hada, every face was beaming with smiles. Farmers say, “Great, look forward to for so many years, we finally have here, dead. From under the child can do homework in the light of.”
Although the installation process is simple, but far away from pastoral households, often only one day to install 12. A total of 40 people in a village, the installation was a whole month. When installed on the local Tibetan people Suk home, he excitedly said: “Before, no electricity, do have to rely on manpower. Now have electricity, we can buy a machine to cut wool shearing, so good and fast. Moreover, after the money, I still want to buy a TV, do not go out, you can know a lot of things out. ”
August 9, 2010, represented by the local government with the power ceremony was held in the village. Herders have to barley wine, Hadad dedicated researchers. See the wind turbine to the local changes caused by the heart, the researchers heartily rejoice. Next, the wind turbine will be used widely. Local people said the small wind turbine not only bring light to them, but also brought hope for development.
Deserves attention is that there is no similar domestic and vertical wind power generator manufacturing standards, the Chinese Mechanical Engineering Society Testing Center, said future development of national standards for record of the Enterprises will field strength standard as a reference.
Ling Zhen Wang said V5.0KW home wind turbines characterized by the largest independent portable mobile power generation system, designed and produced two field strength will be low speed for home use of vertical wind power generator.
Then a generator cost? A family a few years to recover the cost? With this general home users are most concerned about questions raised by wind generators wild enthusiasm. Rui said that the current R & D V5.0KW vertical wind power generator is mainly directed against the communications industry, road transportation, electricity and fresh mountain power, field work, border design of these industries, and in the future they will focus on two production production 1KW, 1.5KW power smaller vertical wind power generator to meet the needs of the market vacancy.
According to reports, a low-power vertical-type wind turbine market position will be 3-5 million, the general villa daily consumption in the 30-50 degree / day, 3 to 5 years will be as cost recovery. A vertical-type wind turbine service life of 30 years, lower maintenance costs during the period.
A new wind may be blowing in electricity for New Jersey but there are concerns it may bring a chill to ratepayers.
Gov. Chris Christie today signed an act that aims to facilitate offshore wind power generator for use in the state.
The measure offers financial aid and tax credits to attract private companies to participate in developing wind farms in the ocean. But this effort may also involve significant expense to be passed on to power consumers.
The Offshore Wind Economic Development Act was signed by Christie at a former BP Oil Company facility in Gloucester County, where a port that once held tanks of fuel oil will become New Jersey’s launching point for an ambitious renewable energy program.
Paulsboro Marine Terminal, a port on the Delaware River the state has struggled to revitalize, is envisaged under the legislation as the preferred hub for manufacturing wind turbines. Through these turbines, the state hopes to one day generate 1,100 megawatts of electricity from farms located 12 to 20 miles off the coast.
The act mandates a percentage of electrical power sold in New Jersey eventually be generated by offshore windmills, and offers a mix of financial assistance and $100 million in tax credits to lure companies to build the turbines in Paulsboro and get the project underway.
“A few months ago, I was at the Jersey Shore talking about my renewed feeling regarding no offshore drilling in New Jersey and also that I did not want liquefied natural gas off the state of New Jersey’s coast, either,” said Christie.
“That was well before the events that we saw in the Gulf Coast, and I just think that it makes sense for us to go in this direction, not only because it’s good for the environment, but because it’s going to help us create jobs.”
But even the lawmakers and environmental leaders who surrounded Christie today said the ambitious effort depends on private investment in wind farms and that small wind turbine manufacturing companies be willing to locate in New Jersey. The last turbine firm to enter the region opened in Pennsylvania.
“While there are no guarantees, those states that are most aggressive in promoting polices that promote alterative energy are the ones that will reap the benefits. … New Jersey is now in the best position of any state to benefit,” said David Pringle of the New Jersey Environmental Federation.
Since the offshore wind project materialized three years ago under then-Gov. Jon Corzine, three firms have struck agreements with the state Board of Public Utilities to conduct meteorological tests. Earlier this week, the BPU agreed to let two of them use buoy-monitors rather than erect towers anchored to the ocean floor for the tests.
But no company has yet signed on to build a wind farm. And one major concern about the project is anticipated rate hikes for electrical customers resulting when an infrastructure must be built to integrate wind-generated energy into the power grid.
“I think that every day we’re seeing that wind generators can be made more efficient and more cost effective to ratepayers,” said Christie.
“Over the long haul, what I’m really concerned about is that we continue to hold ratepayers hostage to energy creation which is much more volatile in terms of its prices. What it will ultimately cost ratepayers is open to question still, but we’re going to be working to make it as efficient and effective as we can.”
The New Jersey Business and Industry Association estimates $7 billion to $14 billion in integration costs will be passed onto ratepayers, predicting an exodus of businesses already stressed by high utility bills, high taxes and a recession.
“You not only need transmission lines from the ocean to the shore, but also additional transmission capacity to integrate the home wind turbines. Remember, wind is variable.,” said Jonathan Lesser, an economic consultant for the group.
“You get the least amount of wind in the summer, when you need the most power, so you are going to need a natural gas-fire generation system to back it up,” he said.
Last November, days Jie Group and China State Power and the air damper joint venture power company electricity and clean wind energy in Inner Mongolia China Co., Ltd., responsible for the development of Inner Mongolia Hing’an one million kilowatts wind farm, the first phase of 49,500 kilowatts wind was Inner Mongolia Autonomous Region Development and Reform Committee approval, will and power generation.
To speed up the progress of construction days, the source wind farm, days cleaning the Group invested nearly 600 million yuan in the first production base in Zhuji brand new wind turbine on the production line; in Inner Mongolia Hing’an Tuquan invest 150 million yuan, the professional manufacturer of wind power fan Tower tube, to reduce transportation costs. By the end of December this year, days source wind farm a total of 35 wind turbines will be installed and running.
Up to now, days Jie Group Hing’an and Tongliao City in Inner Mongolia, Ningxia Wuzhong City, Pinghu, Zhejiang, Wenzhou and has made nine million kilowatts wind farm development rights, and is carrying out wind, the wind project resource allocation, approval approval and other preliminary work to develop an annual rate of more than 300,000 kilowatts for wind farm development.
“As a clean energy, wind power generation in the world with an average annual increase rate of 30%, China’s faster, more than 70%.” Edge Yu told reporters in the next three years, space research and development of clean wind power to 3,000 kilowatts and above wind turbine, the formation of annual production in 5 years, more than 1,000 MW of wind power generating units of the national large-scale equipment wind generator manufacturing base, 10 years ranked among the top three wind power manufacturing industry.
Regular maintenance can make devices to keep the best of the state, and to extend fan life. Regular repair and maintenance work of the main elements are: fan couplings between the bolt torque inspection (including electrical connections), the lubrication between the transmission components and various functional tests.
Fan in normal operation, each connected component of the Bolt to run in a variety of vibration of long-term effort which is very easy to loose, so in order not to loose bolts after the cause of local Shouli Bu were cut, we must regularly Bolt torque check of their conduct. In the environmental temperature is lower than -5 ℃, should make it down to the rated torque for tightening torque of 80, and after the temperature is higher than -5 ℃ review. We generally check on the fastening bolts are arranged in non-small air or wind in summer, to avoid the high power fan season.
Fans of the lubrication system mainly dilute oil lubrication (or lubrication of mineral oil) and dry oil lubricating wind turbines (or grease lubrication) in two ways. Fan gear boxes and yaw Gear Box uses a thin lubricating methods, the maintenance is of additional testing and sampling, if the test results show that the lubricant can no longer use, then wind power generator replaced. Generator parts are dry lubricated bearings, yaw bearing, yaw gear and so on. These components run as high temperature, highly degenerate, resulting in bearing wear and tear, regular maintenance must be carried out each time up to its increase. In addition, the generator bearings according to additional doses of a certain number of requests to join, not too much, to prevent too many to squeeze into the motor windings after, the motor burned out.
Regular maintenance of functional testing test key too quickly, emergency shutdown test, hydraulic system component value test, vibration test switch, twisted cable switch test. You can also set limits on the controller, some routine test values. In addition to regular maintenance other than the above three items, but also check the hydraulic oil level, small wind turbines the sensor for damage, the sensor’s power supply is reliable work, brake pads and brake disc wear and so on.
First, the wind power issue is the development of China’s wind power industry prominent bottleneck. According to the China Electricity Council statistics, in 2009 China’s total wind power installed capacity reached 22 million kilowatts, and the network unit is only 16.13 million kilowatts, and the network unit is not more than 1 / 4. Meanwhile, the wind load characteristics determine its difficult to maintain stable and can not synchronize with the power load changes, there must be other wind power commitment to adapt to changes in load demands, to increase power generation capacity adjustment, peak shaving capability and storage capacity. This requires optimization of the power structure, increasing investment and operation of pumped storage units, increase the peaking power construction scale.
In order to strengthen the research and wind forecast, China’s current wind observation tower built about 400 of them. However, this is not enough, but to build wind power generator forecasts and forecast system, need to promote wind power and grid companies to achieve coordination and cooperation. China Electrotechnical Society, honorary chairman of Zhouhe Liang told the reporter, to achieve this step, the national electricity access to assessment, not only the evaluation capacity. Because the installed easy, and the net hard. Once the online assessment targets to achieve power, the state of all aspects of the unit to reward, motivate, including wind farms, power companies, especially power companies. As wind power, mainly rely on power companies to promote.
Wind energy resource-rich areas are mostly small wind turbines local power system, electricity load less, the news on the assimilative capacity of wind power inadequate. To solve this problem, the key is to increase the intensity of cross-network construction.
Zhou Heliang that the development of wind power to the grid and network synchronization with both non-development, the formation of diversified, balanced development pattern. In the wind energy resource-rich areas, construction of wind power base, building a large network, but also small and medium sized wind farm construction according to local conditions, to meet the remote and inaccessible areas of the electricity demand.
Second, the wind power industry, machine wind generators manufacturers still excess capacity, lack of equipment reliability issues. At present, many domestic fans machine manufacturers, hundreds of family traditions, national electric machine has been assembled, manufacturing companies. The market share of 60% of the total concentrated in the gold wind, sharp and East China Steam hands. The three have an annual output of domestic enterprises with more than 2 million kW, and the remaining 40% of the market share of family property to lower the machine nearly a hundred works by intense competition. To prevent redundant construction, the Ministry of Industry in March 2010 issued a wind power equipment manufacturers access to draft standards to improve the access threshold for wind power equipment, reduce excess capacity. Meanwhile, National Grid is also studying the development of relevant technical standards and network specifications.
In this regard, Zhou Heliang that reduce excess capacity should aim at capacity, but also to improve equipment quality, performance, level of direction.
In recent years, Zai policy strongly, supported by technical Yin Jin, China mastered the group Zhizao MW wind turbine technology, and initially formed blades, gearboxes, generators and control systems Zhuyaobujian the wind Dian equipment Chanye chains, You Yu Da Duoshu windmill power businesses once Zhi Zao, light innovation, Chong Yin Jin, light Xishou, Shi wind power for critical equipment and core Jishu subject Guowai, wind power technology independent innovation capability as weaknesses, in particular, key components of quality of equipment Urgent Improvement of Quality . Coupled with the rapid development of China’s wind power industry, launched a large number of fans rushed the equipment from the research and development to the actual running time is shortened, so that lack of preparation as a result of R & D fan is running a series of problems emerged.
Zhou Heliang that equipment reliability issues will affect the development of wind power in China a huge worry. China’s wind power equipment manufacturers need to focus on wind power main and auxiliary machine optimization and matching, to improve equipment reliability should make great effort.
In the rapid growth of wind power against the background of a few years, most enterprises focus Yu make and the wind power industry R & D platform and public technical service system is far from the pace of development of the industry does not , efficient production, learning and research combined technology R & D system still in a primitive being.
The third is the wind farm’s operation and management level is too low. A lot of attention to installed capacity of wind power projects, while ignoring the run. A lot of wind, whether maintenance, repair capability, or maintenance, management capabilities are to be improved.
Exhibition is in the text Noborizawa Library Town Bay, more than 30 wind turbines with the shoreline scattered and arranged, as a beautiful landscape. It is understood that a total investment of 1 billion yuan from the Tang wind power generator project under construction has continued to strengthen services town Zeku, focus on promoting the rapid construction of the project, now a project has completed an investment of 500 million yuan, the first 30 Typhoon aircraft have been implementation and network test power.
Can travel with wind generators, cars can automatically adjust the temperature control system automatically shut down the engine and other green car … … in yesterday’s opening of the 25th National Youth Science and Technology Innovation Competition youth innovation and competition results of the missions abroad exhibition, Chinese and foreign visitors amazing young people whimsy.

System not only for cars, can also be used for toll booths, large vans, small glass greenhouse and other enclosed spaces.
New Concept Car:
According to the traffic stop automatically open
Participating groups in foreign countries, there are many works in the bright spots. India’s English media from a contestant on the concept of the school a “new concept car.” He advocated the use of electronic devices, save fuel and reduce pollution. For example, a red light, the car will automatically turn off the engine to save energy. Another example is installed in the car under an optical sensor, a traffic signal in the vicinity of any (especially more than 60 seconds of lights) lights installed underground. Automatically open when the red light, green light is automatically shut down. The project also demonstrates the car’s engine before the traffic lights to be turned off and be activated when the vehicle traffic to keep a safe distance, the driver only need to control the steering wheel.
